Abstract Biomphalaria snails are instrumental in transmission of the human blood fluke Schistosoma mansoni . With World Health Organization's goal to eliminate schistosomiasis as a global health problem by 2025, there is now renewed emphasis on snail control. Here, we characterize genome glabrata, lophotrochozoan protostome, and provide timely important information biology. We describe aspects phero-perception, stress responses, immune function regulation gene expression that support...
Readers of this journal are no doubt familiar with recent emphases on the transnational nature diasporic communities worldwide. For most part, emphasis has been associated studies migration and conceptually linked to disciplines such as anthropology, sociology cultural studies. The notion populations has, rather recently, enjoyed somewhat a conceptual revival, largely due complex political economic changes that lead substantial numbers emigrants. end result ability emphasise nature, is,...
In recent times there has been discussion about whether studies of tourism are variously a disciplinary, multi-disciplinary or inter-disciplinary pursuit and how these relate to the institutional landscapes practices higher education. For some academics, discourses somewhat arid, but we would contend they vital as serve set epistemological terms references for scholars play not insignificant role in orchestrating knowledge production tourism. This paper revisits concerns relating...
Many parasites modify their host behaviour to improve own transmission and survival, but the proximate mechanisms remain poorly understood. An original model consists of parasitoid Dinocampus coccinellae its coccinellid host, Coleomegilla maculata ; during manipulation, is not in contact with anymore. We report herein discovery characterization a new RNA virus ( D. paralysis virus, DcPV). Using combination RT-qPCR electron microscopy, we demonstrate that DcPV stored oviduct females,...
Scleractinian corals are the most basal eumetazoan taxon and provide biological physical framework for coral reefs, which among diverse of all ecosystems. Over past three decades coincident with climate change, these phototrophic symbiotic organisms have been subject to increasingly frequent severe diseases, now geographically widespread a major threat Although immunity has increasing study, available information remains fragmentary, especially respect antimicrobial responses. In this we...
Discoveries made over the past ten years have provided evidence that invertebrate antiparasitic responses may be primed in a sustainable manner, leading to failure of secondary encounter with same pathogen. This phenomenon called "immune priming" or "innate immune memory" was mainly phenomenological. The demonstration this process remains obtained and underlying mechanisms remain discovered exhaustively tested rigorous functional molecular methods, eliminate all alternative explanations. In...
Abstract The paper is a review of current issues and literature on air transportation as it related to tourism. It focuses three salient facing international commercial transport their resulting implications for global tourist flows. First, the wider aeropolitical environment reviewed. This followed by recent developments in airline operations. Finally, issue carbon pricing aviation addressed. On basis that tourism are intricately linked, advocates forward planning destinations include...
Abstract In this article I explore a theoretical link between return visits and migration using ethnographic data obtained through fieldwork among members of the broader Commonwealth Eastern Caribbean community in Toronto, Canada. Return are periodic but temporary sojourns made by migrant communities to their external homeland or another location where strong social ties exist. As result, conceptual framework revolves around transnationalism as visit is shown be transnational exercise that...
Abstract The article provides a review of the expansion concept security and relationship to tourism. It is argued that has become transformed from one collective common defence embrace notions cooperative security. Despite damage done because United States led invasion Iraq, development structures through collective, multilateral frameworks such as Nations remains important for concerns cover environment, health economic threats. also notes tourism supranational organizations have little...
The broad intent of this paper is to further contribute the existing literature that addresses VFR tourism. It suggests return visit may ultimately be positioned as a form or type travel within larger category tourism, but has built it more clear understanding historic and social contexts processes. other highlight importance relationship between returning visitor, originating from diasporic communities abroad, host community stage for negotiation identities. shown reflect such underlying...
Abstract Background Coral bleaching can be defined as the loss of symbiotic zooxanthellae and/or their photosynthetic pigments from cnidarian host. This major disturbance reef ecosystems is principally induced by increases in water temperature. Since beginning 1980s and onset global climate change, this phenomenon has been occurring at increasing rates scales, with severity. Several studies have undertaken last few years to better understand cellular molecular mechanisms coral but jigsaw...
For many decades, invertebrate immunity was believed to be non-adaptive, poorly specific, relying exclusively on sometimes multiple but germ-line encoded innate receptors and effectors. But recent studies performed in different species have shaken this paradigm by providing evidence for various types of somatic adaptations at the level putative immune leading an enlarged repertoire recognition molecules. Fibrinogen Related Proteins (FREPs) from mollusc Biomphalaria glabrata are example these...
Aerolysins are virulence factors belonging to the β pore-forming toxin (β-PFT) superfamily that abundantly distributed in bacteria. More rarely, β-PFTs have been described eukaryotic organisms. Recently, we identified a putative cytolytic protein snail, Biomphalaria glabrata, whose primary structural features suggest it could belong this β-PFT superfamily. In present paper, report molecular cloning and functional characterization of protein, which call Biomphalysin, demonstrate is indeed new...
Background Among more than 20,000 species of hermaphroditic trematodes, Schistosomatidae are unusual since they have evolved gonochorism. In schistosomes, sex is determined by a female heterogametic system, but phenotypic sexual dimorphism appears only after infection the vertebrate definitive host. The completion gonad maturation occurs even later, pairing. To date, molecular mechanisms that trigger differentiation in these remain unknown, and vivo studies on developing schistosomulum...
Mouse embryonic stem (ES) cells remain pluripotent in vitro when grown the presence of leukemia inhibitory factor (LIF). LIF withdrawal results progressive ES cell differentiation. Here we show that during this differentiation process, part undergo apoptosis concomitant with an activation p38 MAP kinase. To gain insight into events mediated by cells, expression potential candidate genes was analyzed absence or cytokine using a semiquantitative RT-PCR assay. We focused on early response and...
Historically, the prevailing view in field of invertebrate immunity was that invertebrates do not possess acquired adaptive rely on innate mechanisms with low specificity and no memory. Several recent studies have shaken this paradigm suggested immune defenses are more complex specific than previously thought. Mounting evidence has shown at least some (mainly Ecdysozoa) show high levels their responses to different pathogens, subsequent reexposure may result enhanced protection (recently...
Abstract Genetics and epigenetics are tightly linked heritable information classes. Question arises if provides just a set of environment dependent instructions, or whether it is integral part an inheritance system. We argued that in the latter case epigenetic code should share universality quality genetic code. focused on DNA methylation. Since availability methylation data biased towards model organisms we developed method uses kernel density estimations CpG observed/expected ratios to...
